Cambria County jurors deliberated for about two hours Monday before convicting William Cramer, 22, of that charge as well as aggravated assault and assault by a prisoner in the August 2012 death of 28-year-old William Sherry.

Cramer showed no emotion, but his mother and grandmother wept and sobbed into tissues a few rows behind him as the verdict was read.

Prosecutors said Cramer used a torn bedsheet to kill Sherry and tried to make it look like suicide only hours after the victim had been moved into the cell. Dr. Curtis Goldblatt, who performed the autopsy, said Sherry died of strangulation but had been beaten beforehand.

District Attorney Kelly Callihan said she hoped that the verdict would "provide closure for the family."
